Locally Advanced or Metastatic HR+/HER2- Breast Cancer Overview

Locally advanced or metastatic HR+/HER2- breast cancer is driven by estrogen receptor signaling and represents the most common mBC subtype. Because biomarker discordance and acquired mutations are common, comprehensive molecular profiling (ESR1, PIK3CA, AKT1, PTEN, gBRCA) is mandatory. The frontline standard remains CDK4/6 inhibitors combined with endocrine therapy. Upon progression, management relies heavily on precision medicine: PIK3CA-mutated tumors are treated with inavolisib or alpelisib, capivasertib targets PIK3CA/AKT1/PTEN-altered disease, and the oral SERD elacestrant addresses ESR1-mutated, endocrine-resistant tumors. Patients with germline BRCA mutations benefit from PARP inhibitors (olaparib, talazoparib). Crucially, traditional salvage chemotherapy is being rapidly displaced by antibody-drug conjugates (ADCs); sacituzumab govitecan and trastuzumab deruxtecan—now approved even for HER2-low and HER2-ultralow expression—serve as preferred later-line standards. Management remains incurable but increasingly prolonged, requiring bone-modifying agents and early palliative integration to optimize quality of life.
